Value Collection R20200PS Heavy Hex Nut M20 X 2.50

Product Description

The VALUE COLLECTION R20200PS is a heavy hex nut sized M20 x 2.50, manufactured from Grade 2H steel with a bright uncoated finish. Heavy hex nuts feature a wider across-flats dimension than standard hex nuts, providing greater bearing surface and improved torque transfer in high-load fastening applications. This nut is suited for structural bolting, industrial equipment assembly, and general mechanical installations where ASTM Grade 2H specifications are required. It is installed by ironworkers, millwrights, pipefitters, and maintenance mechanics working with heavy structural connections.

This heavy hex nut is used in structural steel assemblies, industrial piping flanges, machinery mounting, and similar high-load bolted connections. The M20 x 2.50 thread size and Grade 2H designation make it appropriate for applications demanding a heavy-duty fastener with verified material strength. Right-hand thread direction is standard for typical bolted assemblies. Sold individually, it suits replacement and low-quantity service needs.

Key Features

• M20 x 2.50 right-hand thread for standard metric fastening
• Grade 2H steel construction meets heavy hex nut strength requirements
• Width across flats of 37.29 mm provides increased bearing surface versus standard hex nuts
• Height of 20.00 mm for added thread engagement depth
• Bright uncoated finish suitable for use as-is or with applied coatings in the field
• Sold as a single unit for replacement or low-volume service use

Compatibility

Designed as an OEM-style replacement heavy hex nut for metric M20 x 2.50 threaded rod, bolts, and structural fastening applications requiring Grade 2H steel.

Installation Notes

Installation is performed by qualified mechanics, ironworkers, or pipefitters using appropriate metric wrenches or impact tools rated for the fastener size. Always verify thread direction and pitch before installation to avoid cross-threading. Follow applicable structural or mechanical code requirements, such as AISC or ASME standards, for torque and inspection procedures. Inspect mating bolt or stud threads for damage or contamination before assembly.
